Terraform module to provision a VPC with Internet Gateway.

This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!


module "vpc" {
  source     = "git::"
  namespace  = "eg"
  stage      = "test"
  name       = "app"
  cidr_block = ""

Full example with terraform-aws-dynamic-subnets:

module "vpc" {
  source     = "git::"
  namespace  = "eg"
  stage      = "test"
  name       = "app"
  cidr_block = ""

module "dynamic_subnets" {
  source             = "git::"
  namespace          = "eg"
  stage              = "test"
  name               = "app"
  region             = "us-west-2"
  availability_zones = ["us-west-2a","us-west-2b","us-west-2c"]
  vpc_id             = module.vpc.vpc_id
  igw_id             = module.vpc.igw_id
  cidr_block         = ""
